Java 通过Google Adwords API获取特定Adwords报表可用字段列表

是否有任何方法可以使用Google Adwords API获取特定报告的所有可用字段列表。我使用的是Adwords API版本201605

比如说,

    selector.getFields().addAll(Lists.newArrayList("CampaignId",
    "AdGroupId",
    "Id",
    "AdNetworkType2",
    "CriteriaType",
    "Criteria",
    "FinalUrls",
    "Impressions",
    "Clicks",
    "Cost"));

这就是我在报告中选择所需字段的方式。但每个报告都有90多个字段可用。我需要选择案例中的所有字段。那么，adwords api中是否有类似于以下代码的内容：

    selector.getFields().addAll(Report.getFields("ReportType")));

如果以后有人遇到这个问题，那么至少在v201708（也可能是更早的版本）中，您可以执行以下操作

public class GetReportFields {

  public static void main(String[] args) throws Exception {
    // Generate a refreshable OAuth2 credential.
    Credential oAuth2Credential = new OfflineCredentials.Builder()
        .forApi(Api.ADWORDS)
        .fromFile()
        .build()
        .generateCredential();

    // Construct an AdWordsSession.
    AdWordsSession session = new AdWordsSession.Builder()
        .fromFile()
        .withOAuth2Credential(oAuth2Credential)
        .build();

    AdWordsServicesInterface adWordsServices = AdWordsServices.getInstance();

    runExample(adWordsServices, session);
  }

  public static void runExample(
      AdWordsServicesInterface adWordsServices, AdWordsSession session) throws Exception {
    // Get the ReportDefinitionService.
    ReportDefinitionServiceInterface reportDefinitionService =
        adWordsServices.get(session, ReportDefinitionServiceInterface.class);

    // Get report fields.
    ReportDefinitionField[] reportDefinitionFields =
        reportDefinitionService
            .getReportFields(ReportDefinitionReportType.KEYWORDS_PERFORMANCE_REPORT);

    // Display report fields.
    System.out.println("Available fields for report:");

    for (ReportDefinitionField reportDefinitionField : reportDefinitionFields) {
      System.out.printf("\t %s(%s) := [", reportDefinitionField.getFieldName(),
          reportDefinitionField.getFieldType());
      if (reportDefinitionField.getEnumValues() != null) {
        for (String enumValue : reportDefinitionField.getEnumValues()) {
          System.out.printf("%s, ", enumValue);
        }
      }
      System.out.println("]");
    }
  }
}
